There were many reasons why Concorde stopped flying, these are mentioned below.

Noise Factor

There were many complaints from public about the noise Concorde made. The noise was not much from the plane but by the supersonic speed, which produced sound like a thunder or a bang.

Cost Factor

The Oil crisis that started in 1970s made it very expensive to operate Concorde, and influenced many to-be operators to reconsider their options.

Technological Constraints

Unlike many other airlines, Concorde still used many analog instrument. And this was one of the reasons Concorde always flew with a flight engineer in every flight.

The 2000 Crash

The crash of Concorde flight diminished the ambition of its operators.

Costly for Passengers

One Concorde ticket costed around one thousand UK pounds, and nearly double for a First class seat, in 1980s. There were not as many customers as were expected to be received.

Non Eco Friendly

A 100-seater Concorde plane burnt 89,000 liters of fuel in a flight, where as other planes carrying about 400 passengers burnt only 59000 liters of fuel, in the same length flight.

These were the reasons why Concorde was retired. But now, it's in the news that a renewed Concorde will be in the air again in 2019. That's a great news!

This is quite amazing. During assembly less that 10,000 holes were drilled.  In a 787, 1 million holes were drilled.

Fuel consumption

20% more fuel efficient than any other similarly sized aircraft.

Emission

It produces 20% less emission than similarly sized aircrafts.

Electrical system

The electrical system of Dreamliner 787 consumes 35% less power from engine that any other similarly sized plane.

Design of 787 Dreamliner

It took 800,000 hours on a supercomputer to design the 787 Dreamliner.

Maintenance cost

It is anticipated that maintenance cost on 787 Dreamliner will be 30% less than any other aircraft.

These were interesting facts about Dreamliner 787. This aircraft comes in three slight variations, namely 787-8, 787-9 and 787-10. The minor differences in these three models is in wing span, height, length, takeoff weight.
